Carmel

As the only high land on the Mediterranean coastline of Palestine the Carmel
ridge gets higher than average rainfall and so is particularly fertile (Isaiah
33:9; Jer 50:19 cf.
Na 1:4).

Nabal was rich and held land there (1
Samuel 25:2); Elijah's contest with the prophets of Baal - which concerned provision of rain -
occurred here (1 Kings 18:19ff.)

Left from Carmel north-east,
below Carmel ridge from south.

This fertility is the point
of the reference to "Carmel's crest" in Am 1:2, while in 9:3, where the phrase parallels the "sea
bed" and follows talk of the sky, it is the steep height
of the ridge that is in view.
